摘要
应用倍频Nd∶YAG脉冲激光,在波长为532nm、脉冲宽度分别为8ns和23ps的条件下,研究了新型富勒氮烯乙酰氨衍生物(N-acetamide1,2-dihydro-1,2-aza-fulerene[60])的反饱和吸收与光限幅特性。实验结果表明,同脉宽为纳秒的激发脉冲相比,富勒烯乙酰氨衍生物对脉宽为皮秒的脉冲限幅效果比较好。
Reverse saturable absorption and optical limiting in new N acetamide C 60 nitride (N acetamide 1,2 dihydro 1,2 aza fullerene) are studies by using double frequency Nd∶YAG pulse laser system with wavelength of 532 nm,pulse width of 8 ns and 23 ps, respectively. Comparing with optical limiting for ns pulse, the experiment result show these new materials have good optical limiting character for ps pulse.
